【解析】

試題分析：短文大意：每年的3月20日是世界水日。根據(jù)美國的一個報道，世界上有一半多的主要河流嚴(yán)重缺水或被污染。黃河，世界上第五大河，在過去的35年里，就沒有流到大海里。同意，埃及的尼羅河，世界上最長的河流，由原來每年的32000000000平方米的流量降低到2000000000.等等。是說明原因造成這樣的現(xiàn)象？主要是由于筑壩和全球變暖導(dǎo)致河流干涸。

【1】F聯(lián)系上句But now it has a serious problem. 和_In most of the past 35 years, it didn't reach the sea.可知這里是舉了一個可怕的例子，所以選F。

【2】C聯(lián)系上句The Nile in Egypt, running 6, 650 km, is the longest river in the world. 和下句Now it is down to 2 billion m' or so. 可知這里該是在說過去它每年要帶來32000000000立方米的水。所以選C。

【3】D聯(lián)系下句Mostly it's damming (筑壩) and global warming that make rivers dry.可知這里是在說它是怎樣發(fā)生的，所以選D。

【4】A聯(lián)系下文Now about 45, 000 of them lie across the world's rivers. They hold back around 15% of the world's fresh water from running to the sea.可知該選A。

【5】B 聯(lián)系上句The glacier (冰川) are becoming smaller.和下句Global warming has had certain effects on water sources (源頭)可知該選B。
